Abstract

The invention discloses an overheating protection type lithium battery, and the lithium battery comprises a shell and an inner core arranged in the shell; a negative plate and a positive column are inserted into the two ends of the inner core respectively, a control cavity is formed in the shell, an external column is inserted into the side wall of the control cavity in a penetrating mode, and a dripping box is fixed to the inner wall of the control cavity; the inner top of the dripping box is connected with a push plate through an extrusion spring, and a power connection rod penetrating through the top of the dripping box is fixed to the upper end of the push plate. The device has the advantages that the two power connection sheets are communicated through mercury, so mercury is connectedinto the whole power supply circuit, and when the device is heated, dichloromethane expands to cause the push plate to extrude the mercury, so the capacity of the mercury connected into the circuit is reduced, the overall current passing rate is reduced, and the electrifying current of the whole circuit is reduced; therefore, the heat productivity of the battery is controlled, self redeeming is effectively completed, and overheating damage to the battery is avoided.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to an overheating protection lithium battery. Background technique [0002] Communication equipment is generally divided into wired communication equipment and wireless communication equipment. Both wired communication equipment and wireless communication equipment are inseparable from power supply facilities. Mobile communication equipment is a typical wireless communication equipment, and its power supply facilities are generally removable storage batteries. The storage batteries of existing mobile communication equipment are generally lithium batteries, which makes the usage of lithium batteries very large; [0003] However, there is a big hidden danger in lithium batteries, that is, overheating will lead to explosions, and the existing lithium batteries generally have the ability to dissipate heat, or use electric heating to prepare external heat dissipation mechanisms...
